The U.S. Cyber Command (USCYBERCOM) on Wednesday officially confirmed MuddyWater's ties to the Iranian intelligence apparatus, while simultaneously detailing the various tools and tactics adopted by the espionage actor to burrow into victim networks. "MuddyWater has been seen using a variety of techniques to maintain access to victim networks," USCYBERCOM's Cyber National Mission Force (CNMF)  said  in a statement. "These include side-loading  DLLs  in order to trick legitimate programs into running malware and obfuscating PowerShell scripts to hide command and control functions." The agency characterized the hacking efforts as a subordinate element within the Iranian Ministry of Intelligence and Security (MOIS), corroborating earlier reports about the nation-state actor's provenance. Also tracked under the monikers Static Kitten, Seedworm, Mercury and TEMP.Zagros,  MuddyWater  is known for its  attacks  primarily directed against a wide gamut of en

Apple on Wednesday rolled out software updates for iOS and iPadOS to remediate a persistent  denial-of-service (DoS) issue  affecting the HomeKit smart home framework that could be potentially exploited to launch ransomware-like attacks targeting the devices. The iPhone maker, in its  release notes  for iOS and iPadOS 15.2.1, termed it as a "resource exhaustion issue" that could be triggered when processing a maliciously crafted HomeKit accessory name, adding it addressed the bug with improved validation. The so-called "doorLock" vulnerability, tracked as CVE-2022-22588, affects HomeKit, the software API for connecting smart home devices to iOS applications. Should it be successfully exploited, iPhones and iPads can be sent into a crash spiral simply by changing the name of a HomeKit device to a string larger than 500,000 characters and tricking the target into accepting a malicious Home invitation. Even worse, since HomeKit device names are backed up to iClou

It comes as no surprise that today's cyber threats are orders of magnitude more complex than those of the past. And the ever-evolving tactics that attackers use demand the adoption of better, more holistic and consolidated ways to meet this non-stop challenge. Security teams constantly look for ways to reduce risk while improving security posture, but many approaches offer piecemeal solutions – zeroing in on one particular element of the evolving threat landscape challenge – missing the forest for the trees.  In the last few years, Exposure Management has become known as a comprehensive way of reigning in the chaos, giving organizations a true fighting chance to reduce risk and improve posture. In this article I'll cover what Exposure Management is, how it stacks up against some alternative approaches and why building an Exposure Management program should be on  your 2024 to-do list. What is Exposure Management?  Exposure Management is the systematic identification, evaluation,

Threat actors are actively incorporating public cloud services from Amazon and Microsoft into their malicious campaigns to deliver commodity remote access trojans (RATs) such as  Nanocore ,  Netwire , and  AsyncRAT  to siphon sensitive information from compromised systems. The spear-phishing attacks, which commenced in October 2021, have primarily targeted entities located in the U.S., Canada, Italy, and Singapore, researchers from Cisco Talos said in a report shared with The Hacker News. Using existing legitimate infrastructure to facilitate intrusions is increasingly becoming part of an attacker's playbook as it obviates the need to host their own servers, not to mention be used as a cloaking mechanism to evade detection by security solutions. In recent months, collaboration and communication tools like  Discord, Slack, and Telegram  have found a place in many an infection chain to  commandeer and exfiltrate data  from the victim machines. Viewed in that light, the abuse of

A new  cross-platform backdoor  called " SysJoker " has been observed targeting machines running Windows, Linux, and macOS operating systems as part of an ongoing espionage campaign that's believed to have been initiated during the second half of 2021. "SysJoker masquerades as a system update and generates its [command-and-control server] by decoding a string retrieved from a text file hosted on Google Drive," Intezer researchers Avigayil Mechtinger, Ryan Robinson, and Nicole Fishbein  noted  in a technical write-up publicizing their findings. "Based on victimology and malware's behavior, we assess that SysJoker is after specific targets." The Israeli cybersecurity company, attributing the work to an advanced threat actor, said it first discovered evidence of the implant in December 2021 during an active attack against a Linux-based web server belonging to an unnamed educational institution. A C++-based malware, SysJoker is delivered via a dr

SMBs and SMEs are increasingly turning to MSSPs to secure their businesses because they simply do not have the resources to manage an effective security technology stack. However, it's also challenging for MSSPs to piece together an effective but manageable security technology stack to protect their clients, especially at an affordable price point. This is where Extended Detection and Response (XDR) comes in and can help MSSPs boost their profitability from SMB and SME and improve their protections. XDR is heating up within the MSSP market as these security service providers stand to gain tremendous financial and operational benefits from this nascent technology. XDR promises far better security outcomes at a lower cost than the current security stack approaches most MSSPs currently have in place. One sticky point that keeps arising in the XDR discussion has to do with the different technology approaches XDR providers rely upon to deliver platform capabilities. Most of us have heard

Amid renewed tensions between the U.S. and Russia over  Ukraine  and  Kazakhstan , American cybersecurity and intelligence agencies on Tuesday released a joint advisory on how to detect, respond to, and mitigate cyberattacks orchestrated by Russian state-sponsored actors. To that end, the Cybersecurity and Infrastructure Security Agency (CISA), Federal Bureau of Investigation (FBI), and National Security Agency (NSA) have laid bare the tactics, techniques, and procedures (TTPs) adopted by the adversaries, including spear-phishing, brute-force, and  exploiting known vulnerabilities  to gain initial access to target networks. The list of flaws exploited by Russian hacking groups to gain an initial foothold, which the agencies said are "common but effective," are below — CVE-2018-13379  (FortiGate VPNs) CVE-2019-1653  (Cisco router) CVE-2019-2725  (Oracle WebLogic Server) CVE-2019-7609  (Kibana) CVE-2019-9670  (Zimbra software) CVE-2019-10149  (Exim Simple Mail Transf

Microsoft on Tuesday kicked off its first set of updates for 2022 by  plugging 96 security holes  across its software ecosystem, while urging customers to prioritize patching for what it calls a critical "wormable" vulnerability. Of the 96 vulnerabilities, nine are rated Critical and 89 are rated Important in severity, with six zero-day publicly known at the time of the release. This is in addition to  29 issues  patched in Microsoft Edge on January 6, 2022. None of the disclosed bugs are listed as under attack. The patches cover a swath of the computing giant's portfolio, including Microsoft Windows and Windows Components, Exchange Server, Microsoft Office and Office Components, SharePoint Server, .NET Framework, Microsoft Dynamics, Open-Source Software, Windows Hyper-V, Windows Defender, and Windows Remote Desktop Protocol (RDP). Chief among them is  CVE-2022-21907  (CVSS score: 9.8), a remote code execution vulnerability rooted in the HTTP Protocol Stack. "In

With the last month of 2021 dominated by the log4J vulnerabilities discovery, publication, and patches popping up in rapid succession, odds are you have patched your system against Log4J exploitation attempts. At least some systems, if not all. You might even have installed the latest patch – at the time of writing, that is 2.17.1, but, if the last rapid patching cycle persists, it might have changed by the time this is published. In the meantime, defenders might have been working overtime to plug Log4J born security gaps, but so did cyber-attackers. Log4J's well-deserved fame also alerted cyber-attackers to a potential entry pathway into their target. And, while log4J will hopefully vanish from the headlines,  cyber-attackers are likely to continue trying to exploit it  in the hope of finding unpatched or incompletely patched targets. As human error still accounts  for 95% of all security breaches , cyber-attackers actively rely on these human errors to exploit them and take advant

Cybersecurity researchers have detailed a high severity flaw in KCodes NetUSB component that's integrated into millions of end-user router devices from Netgear, TP-Link, Tenda, EDiMAX, D-Link, and Western Digital, among others. KCodes  NetUSB  is a Linux kernel module that enables devices on a local network to provide USB-based services over IP. Printers, external hard drives, and flash drives plugged into a Linux-based embedded system (e.g., a router) are made available via the network using the driver. CVE-2021-45608  (CVSS score: 9.8), as the security flaw is tracked as, relates to a  buffer overflow vulnerability  that, if successfully exploited, can allow attackers to execute code remotely in the kernel and perform malicious activities of their choice, according to a  report  shared by SentinelOne with The Hacker News. This is the latest in a string of NetUSB vulnerabilities that has been patched in recent years. In May 2015, researchers from SEC Consult disclosed another

Moxie Marlinspike, the founder of the popular encrypted instant messaging service Signal, has announced that he is stepping down as the chief executive of the non-profit in a move that has been underway over the last few months. "In other words, after a decade or more, it's difficult to overstate how important Signal is to me, but I now feel very comfortable replacing myself as CEO based on the team we have, and also believe that it is an important step for expanding on Signal's success," Marlinspike  said  in a blog post on Monday. Executive chairman and WhatsApp co-founder Brian Acton, who famously urged users to #DeleteFacebook in March 2018 and founded the Signal Foundation along with Marlinspike after he walked away from the social media giant in 2017 over a conflict with Facebook's plans to monetize WhatsApp, will serve as the interim CEO while the search for a replacement is on. Founded in July 2014, Signal has more than 40 million monthly users, in

Lookout , an endpoint-to-cloud cyber security company, have put together their cyber security predictions for 2022.  1  —  Cloud connectivity and cloud-to-cloud connectivity will amplify supply-chain breaches One area organizations need to continue to monitor in 2022 is the software supply chain. We tend to think of cloud apps as disparate islands used as destinations by endpoints and end-users to collect and process data. The reality is that these apps constantly communicate with different entities and systems like software-update infrastructure and with each other — interactions that are often not monitored. In late 2020, the cybersecurity community uncovered one of the worst breaches in recent memory when the  SolarWinds  software-publishing infrastructure was infiltrated. More than 100 organizations, including nine U.S. federal agencies, were compromised by trojanized updates that opened backdoors to their infrastructure. This is a prime example of how a weak supply chain can b

Microsoft on Monday disclosed details of a recently patched security vulnerability in Apple's macOS operating system that could be weaponized by a threat actor to expose users' personal information. Tracked as CVE-2021-30970, the flaw concerns a logic issue in the Transparency, Consent and Control (TCC) security framework, which enables users to configure the privacy settings of their apps and provide access to protected files and app data. The  Security & Privacy pane  in the macOS System Preferences app serves as the front end of TCC. Microsoft 365 Defender Research Team, which reported the vulnerability to Apple on July 15, 2021, dubbed the flaw " powerdir ." Apple  addressed  the issue as part of macOS 11.6 and 12.1 updates released in December 2021 with improved state management. While Apple does enforce a policy that limits access to TCC to only apps with full disk access, it's possible to orchestrate an attack wherein a malicious application could

The European Union's data protection watchdog on Monday ordered Europol to delete a vast trove of personal data it obtained pertaining to individuals with no proven links to criminal activity. "Datasets older than six months that have not undergone this Data Subject Categorisation must be erased," the European Data Protection Supervisor ( EDPS )  said  in a press statement. "This means that Europol will no longer be permitted to retain data about people who have not been linked to a crime or a criminal activity for long periods with no set deadline." EDPS' investigation into Europol's handling of sensitive data commenced in April 2019, with the authority noting that the storage of large volumes of data with no Data Subject Categorisation poses a risk to individuals' fundamental rights and amounts to mass surveillance. The cache is said to contain at least four petabytes,  according  to The Guardian. In addition, the ruling also imposed a six-mon

A study of 16 different Uniform Resource Locator ( URL ) parsing libraries has unearthed inconsistencies and confusions that could be exploited to bypass validations and open the door to a wide range of attack vectors. In a deep-dive analysis jointly conducted by cybersecurity firms Claroty   and Snyk, eight security vulnerabilities were identified in as many third-party libraries written in C, JavaScript, PHP, Python, and Ruby languages and used by several web applications. "The confusion in URL parsing can cause unexpected behavior in the software (e.g., web application), and could be exploited by threat actors to cause denial-of-service conditions, information leaks, or possibly conduct remote code execution attacks," the researchers said in a report shared with The Hacker News. With URLs being a fundamental mechanism by which resources — located either locally or on the web — can be requested and retrieved, differences in how the parsing libraries interpret a URL requ

New research into the infrastructure behind an emerging DDoS botnet named Abcbot has uncovered "clear" links with a cryptocurrency-mining botnet attack that came to light in December 2020. Attacks involving Abcbot, first  disclosed  by Qihoo 360's Netlab security team in November 2021, are  triggered  via a malicious shell script that targets insecure cloud instances operated by cloud service providers such as Huawei, Tencent, Baidu, and Alibaba Cloud to download malware that co-opts the machine to a botnet, but not before terminating processes from competing threat actors and establishing persistence. The shell script in question is itself an iteration of an earlier version originally  discovered  by Trend Micro in October 2021 hitting vulnerable ECS instances inside Huawei Cloud. But in an interesting twist, continued analysis of the botnet by mapping all known Indicators of Compromise (IoCs), including IP addresses, URLs, and samples, has revealed Abcbot's cod

Threat hunters have shed light on the tactics, techniques, and procedures embraced by an Indian-origin hacking group called Patchwork as part of a renewed campaign that commenced in late November 2021, targeting Pakistani government entities and individuals with a research focus on molecular medicine and biological science. "Ironically, all the information we gathered was possible thanks to the threat actor infecting themselves with their own [remote access trojan], resulting in captured keystrokes and screenshots of their own computer and virtual machines," Malwarebytes Threat Intelligence Team  said  in a report published on Friday. Prominent victims that were successfully infiltrated include Pakistan's Ministry of Defense, National Defence University of Islamabad, Faculty of Bio-Sciences at UVAS Lahore, International Center for Chemical and Biological Sciences (ICCBS), H.E.J. Research Institute of Chemistry, and the Salim Habib University (SBU). Believed to have b

Meta Platforms, the company formerly known as Facebook, on Friday announced the launch of a centralized Privacy Center that aims to "educate people" about its approach with regards to how it collects and processes personal information across its family of social media apps. "Privacy Center provides helpful information about five common privacy topics: sharing, security, data collection, data use and ads," the social technology firm  said  in a press release. The first module, Security, will offer easy access to common tools such as account security settings and two-factor authentication. Sharing will provide specifics about post visibility and settings to archive or trash old posts. Collection and Use will give users a quick glance into the type of data Meta harvests and learn how and why it's used, respectively. Lastly, the Ads section will furnish information regarding a user's ad preferences. The learning hub is expected to be initially limited to a s

The digital security team at the U.K. National Health Service (NHS) has raised the alarm on active exploitation of Log4Shell vulnerabilities in unpatched  VMware Horizon  servers by an unknown threat actor to drop malicious web shells and establish persistence on affected networks for follow-on attacks. "The attack likely consists of a reconnaissance phase, where the attacker uses the Java Naming and Directory InterfaceTM (JNDI) via Log4Shell payloads to call back to malicious infrastructure," the non-departmental public body  said  in an alert. "Once a weakness has been identified, the attack then uses the Lightweight Directory Access Protocol (LDAP) to retrieve and execute a malicious Java class file that injects a web shell into the VM Blast Secure Gateway service." The web shell, once deployed, can serve as a conduit to carry out a multitude of post-exploitation activities such as deploying additional malicious software, data exfiltration, or deployment of r
